The word ‘dendritic’ is associated with—

b) wind

c) glaciers

d) waves

Answer: (a)

Dendritic drainage systems are the most common form of the drainage system. The term Dendritic comes from the Latin word 'dendron', meaning tree, due to the resemblance of the system to a tree.

In a dendritic system there is one main river (like the trunk of a tree), which is joined and formed by many smaller tributary rivers.

Dendritic systems form in V-shaped valleys; as a result, the rock types must be impervious and non-porous.
